7 x 5mm High Frequency Low Jitter HCMOS Clock Oscillator

XOA91 series oscillators are designed to provide an ultra-low phase

noise and loww jitter HCMOS output at high frequencies from

125MHz to 260MHz. An enable/disable function is standard and the

oscillator may also be specified with a power down function.
